Procedure

tert-Butyl (5S,12S)-12-[(R)-[(3R,4R,5R)-3,4-bis{[tert-butyl(dimethyl)silyl]oxy}-5-(2,4-dioxo-3,4-dihydro-1(2H)-pyrimidinyl)tetrahydro-2-furanyl](hydroxy)methyl]-5-isobutyl-3,6-dioxo-1-phenyl-2-oxa-4,7,11-triazatridecan-13-oate (9 mg, 0.0099 mmol, obtained from Example 6) was hydrogenated in methanol (2 ml) using 10% palladium on carbon (7 mg) under atmospheric pressure to provide tert-butyl (2S,3R)-2-[(3-{[(2S)-2-amino-4-methylpentanoyl]amino}propyl)amino]-3-[(3R,4R,5R)-3,4-bis{[tert-butyl(dimethyl)silyl]oxy}-5-(2,4-dioxo-3,4-dihydro-1(2H)-pyrimidinyl)tetrahydro-2-furanyl]-3-hydroxypropanoate (5 mg, 65%) as a pale tan amorphous solid.
